Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987874, here are decompositions:

5 + 987869 = 987874
23 + 987851 = 987874
53 + 987821 = 987874
71 + 987803 = 987874
281 + 987593 = 987874
383 + 987491 = 987874
401 + 987473 = 987874
491 + 987383 = 987874

Showing the first eight; more decompositions exist.
